Automation Case Studies

Real projects. Real results. Every case study below documentes an actual automation system I built — the problem, the solution, the tech stack, and the outcome.

01

AI Lead Qualification System

Make.com OpenAI GPT-4 HubSpot Slack
Results
✓ Lead response time: 4 hours → 90 seconds
✓ Sales team hours saved: 15+ hours/week
✓ Lead qualification accuracy: 92%

The Problem

The client was receiving 80–120 inbound leads per day from multiple sources (website, Meta Ads, Upwork, referrals). Their sales team was manually reviewing each lead and deciding whether to follow up, which took up to 4 hours and caused hot leads to go cold.

The Solution

I built a Make.com automation that captures every inbound lead, sends the lead data to GPT-4 with a custom qualification prompt, receives a lead score (1–10) and reasoning, then routes hot leads (7+) directly to the right sales rep via Slack instant notification while creating the HubSpot deal automatically. Lower-score leads enter a nurture sequence.

Tech Details

Multi-source webhook aggregation → OpenAI API (GPT-4) for scoring → HubSpot Contact + Deal creation → Conditional routing in Make.com → Slack notification with deal link and AI summary.

02

Stripe → HubSpot CRM Automation

Stripe API Make.com HubSpot Slack
Results
✓ 12 hours/week saved on manual CRM updates
✓ 100% payment event coverage in CRM
✓ Onboarding sequence delay: 2 days → instant

The Problem

A SaaS company's finance and customer success teams were manually checking Stripe for payment events and then updating HubSpot contacts, creating deals, and triggering onboarding emails. This took 2–3 hours daily and frequently had 1–2 day delays before new customers received onboarding.

The Solution

I built a complete Stripe webhook processor in Make.com that handles 8 different Stripe events: payment.succeeded, subscription.created, subscription.cancelled, invoice.payment_failed, customer.updated, and more. Each event type triggers specific HubSpot actions — deal creation, property updates, workflow enrollment — and Slack alerts for the relevant team.

Tech Details

Stripe webhook endpoint → Make.com router (8 branches) → HubSpot API (contacts, deals, properties) → HubSpot workflow triggers → Slack channel notifications. Full error logging with Make.com error handlers.

03

AI Product Data Extraction Pipeline

Make.com OpenAI Airtable Python
Results
✓ 8 hours/day of manual data entry eliminated
✓ Data processed: 500+ items/day
✓ Extraction accuracy: 97%+

The Problem

An e-commerce business received supplier product catalogs as PDFs and unstructured emails. Employees spent 8+ hours daily manually extracting product names, SKUs, pricing, dimensions, and specs into Airtable. Errors in this process caused fulfillment issues.

The Solution

I built a pipeline that monitors a Gmail inbox for supplier emails, extracts attachments, sends document content to OpenAI with a structured extraction prompt, and automatically creates/updates Airtable records with the extracted data. Python scripts handle PDF parsing for complex catalog formats.

Tech Details

Gmail watch → Make.com → Python PDF parser (Cloud Function) → OpenAI GPT-4 structured output → Airtable upsert (with deduplication) → Slack confirmation. Full error logging and human review queue for low-confidence extractions.

04

WhatsApp Lead Automation System

WhatsApp API Make.com GoHighLevel OpenAI
Results
✓ Lead-to-call conversion: 3x increase
✓ First-touch response: instant vs 6+ hours
✓ Manual follow-up eliminated entirely

The Problem

A real estate agency generated leads from Facebook and landing pages, but follow-up happened via manual WhatsApp messages sent hours later. By the time agents messaged, most leads had already been contacted by competitors.

The Solution

I built an automated WhatsApp drip sequence triggered instantly on lead capture. Using the WhatsApp Business API, leads receive a personalized first message within 30 seconds, followed by a 5-step sequence over 72 hours. Reply detection pauses the sequence and notifies the assigned agent in real-time.

Tech Details

Facebook Lead Ads → Make.com → GoHighLevel contact creation → WhatsApp Cloud API (instant message) → 5-step delayed sequence (Make.com scheduler) → Reply webhook detection → GHL conversation + agent notification.

05

Google Sheets AI Data Parser

Google Sheets OpenAI Make.com Apps Script
Results
✓ 3 hours of data categorization/day → 0
✓ Processing time: 1000 rows in under 4 minutes
✓ Categorization accuracy: 94%+

The Problem

A marketing agency received weekly raw performance data in Google Sheets from clients — unformatted, inconsistent naming, missing categories. An analyst spent 3+ hours every Monday normalizing, categorizing, and reformatting data before it could be used for reporting.

The Solution

I built a Google Apps Script + Make.com solution that triggers on new spreadsheet uploads, batches rows in groups of 20, sends each batch to OpenAI for intelligent categorization and normalization, then writes clean structured data back to the target sheet automatically.

Tech Details

Google Apps Script trigger → Make.com webhook → Row batching (20 rows/request) → OpenAI structured output (JSON schema) → Google Sheets API write-back → Summary Slack notification with row count and confidence stats.
